Jim Hunt at 22:10 PM on 21 April 2021Why scientists shouldn't heed calls to 'stay in our lane'
Scientists are not staying in their lane these days. They are protesting, or attempting to at least. However it seems the "powers that be" aren't very keen on that idea:

That article in the online version of the UK's Guardian newspaper was "redacted" shortly after publication on Monday.

Voyisz @408,
You quote the OP which is making the point that Ocean Heat Content is the big recipient of the global energy imbalance caused by AGW (rather than the warming which results in surface temperature increases which is a minor recipient).
You follow that by the assertion that it is all about energy rather than temperature which is true but not greatly relevant as Ocean Heat Content is effectively a temperature thing.
And then you introduce the concepts of PE & KE.
Surely PE & KE are red herrings. Is there some part of the global system where mass is increasing in altitude? Are there parts of the global system where stuff is whizzing about faster? In energy terms, any such change globally (if at all) will be miniscule enough to be entirely irrelevant, thus the red herrings.

@ Marcin
I'm located in the US and when I click on the link it takes me to my YouTube account and once the video loads it states "This video may be inappropriate for some users” I have the option to click on the link below the warning that states: "I understand and wish to proceed".
It's sickening to me to see what my country has become. This video puts it in the spotlight. As a biological and medical scientist I am disgusted by the anti-science I see here in the US. We are seriously considering leaving this country.
Just last night I visited a forum I used to participate in trying to educate the climate deniers. I was astounded with the human caused climate denier comments. There's no getting through to a person with a climate denier mind. I wanted to jump in and correct all the distortion of facts and disinformation, but I realized I never want to waste anymore of my time on a forum with people of that mindset. I wasted years on there and the same people are parroting the same BS.
I digress. -

Vonyisz:
Interesting questions. Most of your questions are answered in other posts here on Skeptical Science.
First I would point out that the OP you are responding to was written in December 2007. Since then, as the OP correctly predicted, the temperatures have risen substantially and no-one seriously claims that the temperature is not increasing any more.
There are indeed many metrics that can be measured for heat content of the entire Earth. Most or all of them are measured. For a general audience, like here on Skeptical Science, the surface air temperature is easiest to explain and relates to peoples lives best. The total ocean heat content (all the way to the bottom) is probably a more scientific measurement but does not relate to people as well. Global warming warms the ocean all the way to the deepest depths. In general, the warming is slower the deeper you go.
I recently saw an article (sorry no cite) that said the surface ten meters or so of land has heated up more than scientists thought. As you point out measuring the heat content of soil is difficult, but scientists make the best estimates thay can. Scientists are contually improving heat measurements. Skilled scientists know these measurements and consider them but for the average man on the street (or woman) the surface air temperature means the most. The surface air temperature is noisier than ocean heat content but people relate to air temperatures better.
I have seen calculations similar to yours about melting the ice in the Antarctic (or Greenland). The point is that if all the ice in the Antarctic melted 65 meters of sea level rise would result!! So if only 0.1% of the Suns energy melted ice it would result in 6 centimeters of sea level rise per year! What a disaster that would be.
It turns out that scientists working full time on these difficult questions can reach fairly good approximations of all these measurements. Sometimes a new measurement changes the picture a little (like the land measurements mentioned above), but overall where the heat goes is well known. If you ask about a single one of the measurements you mentioned above perhaps someone can give you a citation. You have too many questions here to specifically answer them.

Eclectic at 06:05 AM on 21 April 2021It hasn't warmed since 1998
Vonyisz @408 :
You have gotten yourself all tangled up. Please step back and look at the overall picture ~ and at what has changed over the past (say) 150 years in our modern world.
The mean sea-level has risen, and continues to rise. The amount and distribution of planetary ice has reduced, and continues to reduce. The planet is warming ~ warming in ocean, topsoil, and lower troposphere. All the regions where plants & animals live.
You do not need to know worldwide soil temperature "all over the earth at a depth of one meter". Unnecessary detail !
But you do need to know the overall trend of warming ~ how large it is, what is causing it, and what we should do to counteract it. Over many decades, the climate scientists have discovered the trend, and its causations.

Vonyisz at 01:51 AM on 21 April 2021It hasn't warmed since 1998
I would have a methodological questions. As this text suggests:
„To claim global warming stopped in 1998 also overlooks a simple physical reality - the land and atmosphere are just a small fraction of the Earth's climate (albeit the part we inhabit). The entire planet is accumulating heat due to an energy imbalance. The atmosphere is warming. Oceans are accumulating energy. Land absorbs energy and ice absorbs heat to melt. To get the full picture on global warming, you need to view the Earth's entire heat content. More than 90% of global warming heat goes into warming the oceans, while less than 3% goes into increasing the atmospheric and surface air temperatures. Nuccitelli et al. (2012) showed that the Earth has continued to heat up since 1998.”
– global warming is not really about temperature, but about the amount of energy.
But this is often misunderstood. Throughout the media, global warming is portrayed as if it could be characterized by changes in temperature.
Q = c * m * ΔT, but here c is not an exact value, consider large pressure and temperature differences
E (pot) = m * g * h, E (kin) = (m * v ^ 2) / 2
And I would have more questions here.
1. What do we refer to the amount of energy? Atmosphere? The kinetic and potential energy of air? With or without hidden heat? (The equivalent potential temperature (theta-e) is the temperature a sample of air would have if all its moisture were condensed out by a pseudo-adiabatic process (i.e., with the latent heat of condensation being used to heat the air sample), and the sample then brought dry-adiabatically back to 1000 hPa.) Surface? How deep? One meter? More? Caves? Groundwater that has a connection to the surface? Top 200 meters of oceans? Or the whole ocean? Energy stored in salinity and depth? Ice? Melting or freezing energy? Potential energy?
1.conc. Average global temperature? Why? When misleading in light of the above: the amount of energy (no matter how we determine what we include in it) is not equal to temperature. Thus, a change in temperature cannot be equal to a change in the amount of energy! Not me saying that. The quoted text does this.
2. We determine what we want to measure. Can it succeed? Can we assign a global average to the temperature of the entire earth? When I buy myself a pair of pants, at least three metrics help me with that. And do we characterize the average temperature of the earth (or rather the total amount of energy) with a single data? Even if we do, what are we going to do with it? What usable speech data does this tell us? This is because exactly what spheres are included in the total energy calculation are closely related to this data. If we calculate this as accurately as we wanted, what can we say about how long this accuracy has been available to us in the past? 10 years ago? 100 years?
2.atm. Do we really measure the temperature and humidity and density of the entire atmosphere? Do we really know the temperature of the earth's surface all over the earth at a depth of one meter?
2.surf. Do we know how much energy is stored in that part of the earth’s surface that is involved in the processes detailed here, absorbs sunlight, and largely heats the atmosphere? Do we know its density? Do we know your specific heat? Do we know its water content? Maybe it's not just the top one that counts? Could it be several meters in some cases? Who can say that? How to calculate? If someone says something, what to expect from him? How do you justify his theory?
2.oce. Do we know the temperature and the amount of dissolved salt everywhere in the oceans? Of course, we don't have an instrument everywhere, we fill in the missing data with approximation calculations. What is the ratio of the total error rate caused by the approximate calculations to the percentage of change to be examined? I read in several places that only the top 200 meters of the oceans matter in terms of global warming. Others write 100 meters. Many people write that the deep ocean has only long-term effects, it doesn’t count in the heat balance in the short term. Why a hundred? Why two hundred? Why doesn't it matter? The limit drawn here seems very arbitrary to me, and in terms of the change in total energy ... it is important to decide and justify: whether or not to include the deep ocean in the energy balance when examining global warming!
2.conc. I see a lot of temperature charts pros and cons. This is how the temperature goes up or how the earth cools. But none of the camps really show how the total amount of energy on earth measured according to the principles detailed above has changed, at least in the last 10-20 years, where perhaps we already have evaluable data in this regard. How can we start a scientific debate without clarifying the framework? The concepts? Principles of repeatable measurements? How is the data processed? Both camps bombard the media with marketing texts that pick it up as raw material and distort it so that it will no longer be completely untraceable to the average person.
3. A degree of warming of the whole ocean is approx. on the order of 10 ^ 24 Joules. Melting the ice of Antarctica would absorb 10 ^ 24 Joules of energy. A degree of warming of the dry air is on the order of 10 ^ 21 Joules. The Sun kisses the Earth with 10 ^ 24 Joules of energy in one year.
Based on these, the scare that the entire Antarctic ice sheet will melt soon seems rather doubtful. This event would eliminate the amount of energy in a whole year of solar radiation (of the same order of magnitude). This needs to be justified! While land ice heats the air when it forms and cools the air when it melts, the formation of coastal ice hanging in the ocean heats both the surface of the ocean and the air, but its melting typically cools the deeper layers of the ocean. Interestingly, land ice can be coastal ice. I hope I use good concepts. The direction of energy as a whole: heat is transferred to the atmosphere from the deeper parts of the ocean. People with CO2 can't warm up the ocean as a whole, just the top few hundred meters. And that is my next question. Are we counting the incoming solar rays and the outgoing infrared rays in the total amount of energy on earth? For example, the city is 35 degrees Celsius in vain if objects are 50-70 degrees Celsius and radiate heat unbearably to humans, while the same 35 degrees in the forest is unpleasant but tolerable because here the temperature of the objects is not higher than the air temperature. Here, the air temperature alone is very misleading. And sorry for the analogy, do we count the energy on the ocean heat transfer road to the total amount of energy on earth? I would like to draw attention to a trap. When the ocean conveyor delivers less energy, the average temperature in the upper part of the ocean is lower, but in this case heat is trapped around the Equator and the poles cool. On the other hand, with higher energy transport, the surface temperature of the oceans increases, most of the excess heat arrives at the poles from around the Equator, so significant warming begins here, more significant than at the Equator. However, the excess heat at the poles also means that the earth's surface can radiate over a larger surface at a higher temperature (T ^ 4). Overall, more heat is dissipated compared to when the capacity of the oceanic strip was smaller, disregarding other factors. I am thinking in particular here that, as soon as the Arctic ice melts in the summer, this process must be taken into account, because the thermal insulating effect of the ice will disappear.
3.conc. Is it conceivable that a change in the latter will affect a change in the distribution of the total amount of energy on earth? Perhaps these and other relevant metrics can bring the understanding and explanation of global warming closer to both experts and the average person? -

Eclectic at 20:45 PM on 20 April 2021Why scientists shouldn't heed calls to 'stay in our lane'
Sad for Ben Santer to lose a friend to "trumpism".
I have lost a cousin who has cut himself off from his siblings & extended family ~ in part because Global Warming is a Hoax. Add some conspiracy ideation and a "suspicious mind" about the (presumed) nefarious intent of his siblings/cousins. His adult children try to keep their heads down and wait for it all to pass (but they don't seem hopeful).
He is not insane in the strict medico-legal sense, but IMO he is intellectually insane. Nor do I think he has an organic brain dysfunction and/or early dementia, as far as I can tell. But judging by the shenanigans on the internet (especially the echochamber of GreenHouse denialism at WattsUpWithThat ) his is not a wildly uncommon case. Additionally, there must be millions who go along for the ride, as a matter of identity politics.
Fortunately, I rarely encounter flagrant denialists in everyday real life. But obviously they exist, even in the higher echelons of government.
The real question is :- Which way is the tide running? And are politicians starting to see the light . . . or are they merely responding to increased public & media pressure, and are simply dissembling while hoping they're dealing with a transient wave of publicity.
From what I've seen during the past 5 months [ i.e. since mid-November 2020] , the denizens of WUWT are a bit glum, but consider themselves to be bravely holding out against all this unscientific AGW nonsense (and its underlying Marxist World Revolutionary push). Bravely holding out until the public is brought to its senses by sky-rocketing electricity prices and the inevitable arrival of decades of drastic Global Cooling. Due soon.

nigelj at 11:54 AM on 20 April 2021Wind and solar energy are job creators. Which states are taking advantage?
We dont have an automated economy, so we need to create jobs so people can build the automated ecomomy. And to build the power sources that fuel the automated economy (renewables). You cant put the cart before the horse.
However the completely automated economy is probably a fantasy. I doubt the world has enough material resources for millions, perhaps billions of robots etcetera because that is what you are talking about. The services sector will still employ quite a lot of people.

David-acct at 10:59 AM on 20 April 2021Wind and solar energy are job creators. Which states are taking advantage?
Withut critisizing Ig guy above, - The linked article provides excellent information about the number of jobs in each state by source of electric generation. Below are some pertinent data from the Texas and California which have some of the largest penetration of renewables in their electric generation mix.
The electric generation mix in Texas is a approx 25% wind and approx 45% from natural gas. The attached link cited in this article shows the employment numbers are approx 25,500 for wind generation and approx 7,900 for jobs in electrical generation from natural gas. that equates to approx 5 jobs in wind generation to produce the same amount of electricity from natural gas.
The same report cited in this article shows jobs in the solar sector is approx 124,000 of which 50,500 is in solar construction leaving approx 74,000 for electric generation from solar, where as 20,500 jobs are in the natural gas electric generation sector. The electric generation mix in California is approx 15% while electric generation from natural gas is approx 34%. That equates to approx 9 jobs in solar to produce the same amount of electricity from natural gas.

michael sweet at 00:44 AM on 20 April 2021Is Nuclear Energy the Answer?
John O'Neill:
According to this World Nuclear News article from September 2020, the Terrapower sodium cooled reactor you refer to has not been submitted for certification. They hope to start commercialization by the end of the decade. Likewise Canadian Terrestial Energy is a start up with a paper design and little else.
Can you provide references that support your claim these reactors are more than paper designs?
The storage of the Terrapower reactor would only raise output less than 50% for 5 1/2 hours. That doesn't sound like cheap storage to me. Both these designs have signficant problems to deal with for example: liquid sodium reactors have chronic sodium fires and molten salt reactors have no materials to manufacture valves.
Since nuclear power plants have to be run full out all the time to be economic they do not fit into a renewable system. The claim that with storage the reactors fit well with wind is simply propaganda from the industry. In addition, they are too expensive to build and run and take too long to build. Even the builders of the reactors you mention do not expect their designs to be buildable before 2030 best case. We need to change over to renewable energy before those reactors will be ready.
When a nuclear power plant is shut down it takes time to build replacement renewable energy. If we really try to build out wind and solar there will be a substantial decrease in carbon emissions in a short period of time. As more and more renewable energy is built out emissions have already started to decrease.

...and yet the people arguing against taking action on climate, or other environmental issues, keep using the excuse that the proposed actions are "job killers".
And the people employed in the fossil fuel industry worry about losing their jobs and being unable to buy the essentials of life. Being able to provide them with alternative jobs is a benefit, not a cost.
Automated production isn't free - it takes huge amounts of capital investment. The idea that automation will make stuff for free is a pipe dream.
-
Ignorant Guy at 12:14 PM on 19 April 2021Wind and solar energy are job creators. Which states are taking advantage?
Very often I see the argument that something is good because it creates job. That is a mistake. Work is not an asset, it's a cost. Imagine we could produce all goods and services we need without any person doing any work because exactly all production was automated. Then all goods and services would be free. On the other hand, imagine that some sector, e g renewable energy production (or fizzy drinks), would create an enormous amount of jobs, say 8 billion new jobs. Then, unless the rest of the production was automated, everyone would be busy producing renewable energy (or fizzy drinks) and nothing at all except renewable energy (or fizzy drinks) would be produced. Work is a cost because work is the price we pay to keep the production going. It's not work that is an asset but labour. But labour is an asset only as long as work needs to be done.

Should we discriminate against certain people, such as criminals?
Is "discrimination" automatically a bad thing? Are you discriminating against discrimination? ;-)
Equity - like probity or disinterested - is one of those underused words. And critical thinking is aided by usage of precise words, in the handling of concepts. In a sloppy way, words are too often used as slogans. Phrases, too, can suffer that fate ~ "The Climate Is Always Changing" is an example of a slogan used to short-circuit real meaning.
Yes, the word equality also is too often used as an unthinking slogan. Equity is a rather legalistic word ~ but it deserves prominence when we consider the world's problems.

The view that an increase from 2 billion to 8 billion people breathing out billions of tons of CO2 is carbon neutral cycle and not a problem is interesting. Using that logic, we could say that burning fossil fuel and building concrete infrastructure is simply releasing CO2 back into the atmosphere from whence it came is a carbon neutral cycle too - albeit on a longer time frame.
Moderator Response:[TD] The long time needed to recycle the carbon injected into the atmosphere from burning fossil fuels in fact is the problem. Read the post about breathing, and if you want to comment more on that topic do so there not here.

John ONeill at 23:39 PM on 16 April 2021Is Nuclear Energy the Answer?
'In a renewable energy world baseload power is very low value. Peak power on windless nights is most valuable. Current baseload plants are dinosaurs.' At least three nuclear designs going through certification - the Bill Gates/Terrapower sodium cooled reactor, the Canadian Terrestrial Energy molten salt graphite design ( based on the Oak Ridge Molten Salt Reactor Experiment ), and Moltex (an innovative fast reactor using plutonium chloride salt in fuel tubes similar to those of current reactors) - propose directly heating nitrate salts, as used in concentrating solar power plants. This would enable the reactor part to make heat 24/7, at ~ 500 megawatts, but store it to make power on demand at 1000 or 1500 MW, with only an additional turbine or two. This would integrate well with wind, which usually manages a 30-40% capacity factor. This would be much better than the current scenario, where part time wind, backed by natural gas, is undercutting baseload nuclear. Overall emissions rose after the closure of Vermont Yankee and San Onofre. They will certainly go up again when Indian Point, near New York, closes. Andrew Cuomo, governor of NY state, admitted that the closure of upstate reactors would lead to more gas being burnt, but would not relent on forcing the Indian Point reactors, which provided about a third of the city's power, to shut. They had been in the process of getting a twenty year licence extension, and could probably have had a further twenty years, as have several similar power plants.

wilddouglascounty at 23:36 PM on 10 April 2021The choice is clear: Fair climate policy or no climate policy
It seems to me that this article does an excellent job of describing the complexities of what true equity is and where the inequalities exist in the regional, national and international spheres. Alas, these well described complexities could also be used to argue precisely the opposite conclusion: that the inertia that arises from built in reinforcements for the advantaged that are inherent in those inequalities is the primary reason things have not changed in a timely fashion so far. So if we want to be able to change things, we must work within the framework of inequality in order to make it worthwhile for those who have concentrated power and resources to adopt the low carbon economy required to reduce carbon emissions.
I'm not trying to defend the inequalities that have been created through the fossil fuel economy; indeed these inequities make it even more difficult not to see the transition to a low carbon economy as yet another way for those with power to retain it. But I believe we are in an "all hands on deck" time if we are to avoid an even more dire future, meaning that we need to enlist those who benefit from inequity alongside those on the short end. The "haves" have unfortunately but predictably been reluctant to redistribute the concentrated wealth that comes hand in hand with a fossil fuel economy but it will be easier to attain the common good of a low carbon economy if they can be allies instead of barriers. The 'haves' have already shown a willingness to create a 'gated community' version of the future where the 'haves' increase inequality in order to maintain their power, leading sometimes to violence and more/new forms of inequity. Some countries have used governments to reinforce the concentration of economic power in the form of totalitarian/fascist repression, while other countries have used their governments to spread the wealth more equitably. But this has been difficult to maintain considering that all governments are responsive to their own sources of their power and find concentrated power irresistable.
As we look at the technological and cultural challenges of transforming to a low carbon future through such endeavors as Project Drawdown, I think we need to devote similar attention to the barriers that are caused by the concentration of political and economic power that goes with it. Change does not occur unless the barriers to change are removed, no matter how attractive the alternatives are. The barriers to a low carbon future are intertwined with the barriers to equity and I daresay that even if we can remove enough barriers to create a low carbon future, we will find the barriers to equity even more resistant.

Tom Dayton, Thanks for the insight into the peer review process! Sounds pretty grueling...
I was asking because one of the main responses I get from deniers when I give the studies on consensus, are links to notable deniers going into details on their own reviews about the studies always claiming a smoking gun of trickery and deception on these studies. One usually has to get pretty deep in the weeds to dispel those. I always look for the simpler explanation that makes sense to the possible audience of my discussion. I've usually given up on convincing the other person, but I want to always frame my arguments to appeal to those with a cursury interest and not get mired in the snowing attempts from deniers. It would be good to argue that denier biased "reviews" of studies are not reliable, and the scientific peer review process is much better at catching bad science.

And if there is any issue where transormational change is desperately needed--climate change is it!! Kudos to Skeptical Science for taking this step!! -

This article puts words to my thoughts. An example here in the Upper Hunter Valley,with my local NSW state govt here in Aust unwilling to unshackel from its fossil fuel donations and an election in under 6 mths. The local populace are very pro mines, so a losing stratergy for any politic party if anti coal. People want action on climate change but not if it is too disruptive, ha . https://reneweconomy.com.au/surge-in-new-coal-mine-proposals-in-nsw-triggers-fresh-calls-for-coal-moratorium/ Sometimes I think we get the leaders we deserve- not the leaders we need..

scaddenp at 13:14 PM on 9 April 2021There is no consensus
Note there is more the Naomi Oreskes paper here. It is not clear to me from the context whether the Oreske article was peer-reviewed. Editorial-type and some review pieces in Science journals are not always peer-reviewed, though papers are in Science. However, the Oreske paper was in section called "essays on science and society". Since it was presenting an actual analysis rather than comment, I would guess "yes", but it isnt that clear.
The Oreske conclusion is not substantively different from other peer-reviewed studies of consensus however. It is extremely difficult to challenge the conclusion that a very strong scientific consensus on AGW exists from the evidence.

Karlengle: Perhaps I misunderstood your question. I thought you asked to see the peer reviews of the publications. Are you instead asking how to tell whether a given publication was peer reviewed?

Tom Dayton at 10:02 AM on 9 April 2021There is no consensus
Karlengle: "Peer review" of submissions for scientific publication usually is done double blinded--the reviewers don't know who the authors are, and vice versa. Authors are given the reviews regardless of the final decision of acceptance or rejection by the journal or conference. For many decades, those reviews remained private, as a way to support frankness. But some publications are changing the model to open reviews.
(In fact, at this very moment, I am in hour 10 of 12 hours of a conference subcommittee meeting--fortunately three sessions of four hours. All 37 subcommittee members are watching discussions of each submitted paper by two of those members, summarizing each paper's review by them plus by two to four reviewers who are not on the subcommittee. Substantial effort went into carefully recruiting those two to four external reviewers, curating discussions among those reviewers to clarify disagreements in their reviews, and crafting demanded or suggested revisions to the authors.)

Hi, I have a question about peer reviews. Are there lists somewhere that show who has peer-reviewed studies/papers being mentioned? For example, I have been searching for peer reviews of Naomi Oreske's consenus study, but I'm not having any luck? Any places you can point me to? When offer these studies at online discussions, I invariably get linked to critiques given by bloggers. Of course, these bloggers, being climate deniers offer all sorts of claims of dishonesty and bad studies, but it seems like if these studies where peer reviewed, those reviews would hold much more water than a denier blogger with no real expertise in climate science...

johnd@44
Hi johnd,
CO2 is not the basic buidling block for a carbon based life.
CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth.
Carbons ability to hybridize orbitals is the key factors here, not the CO2 molecule.
It's also Carbon's capability of forming a vast number of compounds, more than any other element, with almost ten million compounds described to date. Carbon's widespread abundance, its ability to form stable bonds with numerous other elements, and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables it to serve as a common element of all known living organisms. Carbon is important because of its ability to form long chain-like molecules (carbon chains form the backbone of organic molecules.
Finally, consider the abundance of carbon in the universe ( 4,600 ppm in the universe) versus the next group 14 element silicon (650 ppm in the universe) and you see that carbon has a unique abilty to hybridize its S and P electron shells, thus making 4 electrons of equal energy level, this proptery of carbon really was the only way to achieve a carbon based life here on earth. Why? Because carbon can form stable bonds with itself, but also with a variety of other types of elements. This is why life is "carbon-based" or predominantly carbon. -

I truly enjoy your responses. I've learned so much from posting the links and comments from the occasional denialist I run across.
I told the Canadian to go ask the Midwest farmers if the extra CO2 in the atmosphere helped their flooded fields in 2019 and the econimic impact it cost. I suggested that while he's at it, please ask the CA farmers if the extra CO2 in the atmosphere helped their drought stricken crops last year and to explain how climate change impacted these events. -

johnd at 20:08 PM on 7 April 2021CO2 is plant food
Perhaps rather than considering that CO2 as being plant food it is more exact to describe it as the basic building block of a carbon based life form, given all life as we know it is just that.
Typically, 99% of the human body consists of six elements, oxygen 65%, carbon 18.5%, hydrogen 9.5%, nitrogen 3.2%, calcium 1.5%, and phosphorus 1.0%. which explains why when the human body combusts, so too with most other materials, all that is left is carbon.

Eclectic at 18:32 PM on 7 April 2021CO2 is plant food
TVC15 @#40 ,
the Canadian denialist has linked to an "amusing" website article showing :-
(A) "Plants have been starved for CO2 at the low levels existing before the industrial revolution". (Which would be why the South American Amerindians have dwelt in semi-arid wastelands for thousands of years rather than discovering the lush vibrant Amazonian Jungle ? )
and (B) "Mankind has been living on the edge of extinction with low levels of atmospheric CO2" . . . since all (terrestrial?) plants die if atmospheric CO2 falls below 150ppm.
I gather that under experimental conditions, plants can survive with less than 150ppm CO2 ~ but this is confounded by many other associated factors that would apply in a real world situation (including very extensive glaciation).
See my comments in #34 above.
But the very low CO2 scenario is moot because of recent anthropogenic CO2 emission. Without current human emissions, the planet would have continued for millions of years before reaching below the 150ppm mark. During that time, "assisted" or natural evolution would likely produce plants adapted to low CO2. Assuming that the humans of the future would decide not to burn a few gigatons of coal occasionally . . . or chose not to use heat to decompose calcium carbonate rock.
Humans "on the edge of extinction" is alarmist hogwash.

TVC15 @#40 ,
undeniably, CO2 is a plant food, and the increased planetary greening is of benefit to insects and goats. Whether the general increased greening is to be beneficial to humans, is an arguable point (see the Lead Article, above).
Also note that some of the greening in India has come from increased irrigation, and some of the greening in China has come from extensive governmental tree-planting programs.
And the greening of past decades may be plateauing out ( I do not have a convenient citation for that).
What is amusing, is how so many prominent denialists will vehemently [and correctly] assert that nearly all life on Earth is supported by the tiny amount of CO2 in the atmosphere . . . yet, minutes later, they will assert that the atmospheric level of CO2 is simply too tiny to affect Earth's climate.

Tom Dayton at 13:22 PM on 7 April 2021An exponential increase in CO2 will result in a linear increase in temperature
Crashed: That sentence is an attempted summarization. Would it be clearer if it were expanded to "...rather than examining only noisy short-term temperature data, we should remove the effects of those other factors on temperature so we can estimate the effect of CO2 alone, then examine how much atmospheric CO2 is increasing."

Eclectic at 12:40 PM on 7 April 2021An exponential increase in CO2 will result in a linear increase in temperature
Crashed @14 ,
Quite right. And it goes in the opposite direction, too ~ some "skeptics" say well-established physics theory (e.g. gravity causing downward acceleration, or CO2 radiational properties causing planetary warming) must be false because whatever-it-is has not yet happened. Or more precisely: has not yet happened "enough" to impress them to a drastic extent.
Rather like the tale of the Optimist who fell off the top of the Empire State Building ~ "25 floors and okay so far . . . 28 floors and okay so far . . . 32 floors and okay so far . . . "
Until the final predictable Splat onto the pavement, the Optimist refuses to make a realistic assessment of the overall situation.
You see that sort of thing very often with "skeptics" ~ the globe isn't warming (enough) . . . the ice isn't melting (enough) . . . the sea-level rise can't accelerate ( because it didn't do so during the previous century). And they turn the logic inside out, to claim this proves AGW & climate science must be fake.
Crashed ~ if you could analyse & explain that sort of stupid thinking, I would be very grateful !

Crashed at 11:01 AM on 7 April 2021An exponential increase in CO2 will result in a linear increase in temperature
Some skeptics have claimed that these projected amounts of warming have not been borne out in the surface temperature changes over the past decade. But there are many factors which impact short-term global temperatures, which may conceal the long-term warming caused by increasing atmospheric CO2. So if we want to know if the IPCC projections are realistic, rather than examining noisy short-term temperature data, we should examine how much atmospheric CO2 is increasing.
That is not really helpful. When you break it down what it says is... some skeptics might say that what's happening on the ground doesn't reflect the theory, so for that, we use the theory to proove that what didn't happen will happen in the future.
You cant use what we expect to see in the future as a rebuttal against what we haven't seen in the past, that seems like abit of a fallacy.

Daniel Bailey at 09:27 AM on 6 April 2021CO2 is not the only driver of climate
Sigh. If only people would stop checking their cerebral cortex at the border to Denierstan: people live in the troposphere, not the thermosphere.
I know they both start with "t", but that's all they have in common.
From NASA scientist Martin Mlynczak:"There is no relationship between the natural cycle of cooling and warming in the thermosphere and the weather/climate at Earth’s surface. NASA and other climate researchers continue to see a warming trend in the troposphere, the layer of atmosphere closest to Earth’s surface."
"Observations have shown that solar flare activity on the surface of the Sun is in the quiet phase of its continuing 11-year cycle. This causes cooling of the thermosphere—a layer of the atmosphere that starts 65 miles above the surface—and will not cause noticeable cooling at the surface"

Please surprise us by demonstrating some actual skepticism.

It's a long Gish-gallop of anti-science, so was there any specific point contained in it that you'd like to see addressed? If you don't narrow it down a little it would require a very long response to debunk the loads of crap written on that page.

Hi. Neophyte here again and I do consider myself that, but I keep trying to learn.
I think this'll be on topic, but possible it should be under "it's the sun". Sorry if I made a mistake.
I ran into this article: https://coldclimatechange.com/carbon-dioxide-is-a-cooling-gas-according-to-nasa/
Let me know what you think of it. I'll keep reading.

MA Rodger,
It may be too late for that. Down the comment thread at NTZ she seems to argue against space being a heat sink.
Other commenters refer to G&T as if it held any value.
It seems NTZ is every bit as much a waste of time as WUWT.
